Baja Fish Taco with Turmeric Corn Tortilla & Avocado Crema
Turmeric Masa Tortilla
Why Traditional Masa Harina May Be Better Tolerated Than Regular Corn Products
Nixtamalization changes the grain
Masa harina is made from corn that has been nixtamalized—soaked and cooked in an alkaline solution (traditionally lime/calcium hydroxide) before grinding.
This traditional process:
Improves digestibility
Reduces certain antinutrients
Increases mineral availability, particularly calcium
Alters the corn's protein and starch structure
Has been shown to improve nutrient absorption compared with untreated corn
From a functional nutrition perspective, nixtamalized corn is a very different food from highly processed corn chips, corn syrup, corn flakes, or refined corn starch.
Made with traditionally nixtamalized masa harina and turmeric. The nixtamalization process enhances mineral availability and creates a flavorful whole-grain tortilla that pairs well with the fermented slaw and omega-3-rich fish. This Baja-style taco combines grilled fish, probiotic-rich slaw, and anti-inflammatory turmeric tortillas. It’s fresh, vibrant, and surprisingly easy for home cooks.

Wellness Highlights
Fermented cabbage: supports gut microbiome
Wild fish: rich in omega-3 fatty acids
Turmeric: anti-inflammatory curcumin
Avocado: heart-healthy fats and fiber
Whole-food preparation matters
Many concerns about "corn causing inflammation" stem from:
Highly processed corn products
Excess omega-6 intake from industrial seed oils is often used with corn snacks
Blood sugar dysregulation from refined corn ingredients
Individual food sensitivities
A traditional masa tortilla contains:
Whole-ground corn
Fiber
Resistant starch
Minimal ingredients
This differs substantially from ultra-processed corn-based foods.
Context matters for gut health
For individuals with significant gastrointestinal symptoms, active IBD flares, severe dysbiosis, or known corn sensitivity, even traditionally prepared corn may not be appropriate.
However, many practitioners find that clients tolerate:
Nixtamalized corn tortillas
Organic heirloom corn products
Freshly prepared masa
better than conventional processed corn products.
